Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial field of application) The present invention relates to a suction grill of an indoor unit of an air conditioner, and particularly guides and holds an air filter mounted parallel to the suction surface. For a suction grill having a filter guide for

(Prior Art) Generally, in a wall-mounted indoor unit of an air conditioner, an air filter for dust protection is attached to a suction grill of the indoor unit.

As shown in FIG. 6 and FIG. 7, a conventional indoor unit a of this type has an indoor heat exchanger (not shown) and the like inside, and a suction grill whose front is an air intake port. It is partitioned by b and laterally by a side plate c, and air after heat exchange is blown out from below.

As shown in FIG. 8, the suction grill b has an air filter e attached to the back side thereof in parallel with the suction surface d. Therefore, a filter guide g for guiding the air filter e in the insertion / removal direction (vertical direction) at both ends f thereof.
Is provided. Therefore, when inserting the air filter e for new installation or replacement, the edge portion of the air filter e is inserted to a predetermined position while engaging both side edges f of the suction grill b and the filter guide g. It will be.

(Problems to be solved by the invention) By the way, recently, the suction grill b is usually formed of a synthetic resin. In this case, since the filter guide g extends in an L shape from both ends f of the suction grill b, that is, in parallel with the suction surface d, in order to support the air filter e so as to sandwich the air filter e from both sides, It could not be integrally molded with the grill b. For this reason, in the prior art, as shown in FIG. 9, the main body h of the suction grill b and the filter guide g are separately molded, and are adhered to each other with an adhesive. . However, when an adhesive is used, it takes time to complete the adhesion, and it is necessary to strictly control the amount of the adhesive so that the adhesive does not overflow, and there is a problem that defective adhesion may occur. there were.

In view of the above circumstances, the present invention was devised to provide a suction grill that can be manufactured without using an adhesive.

[Structure of the Invention] (Means for Solving the Problem) The present invention relates to a suction grill provided with an indoor unit of an air conditioner and having a filter guide for guiding an air filter in parallel with a suction surface. The guide connecting portions formed at both ends of the suction grille are integrally provided with a guide pressing portion agent facing the guide connecting portions, and the filter guide is provided with an engaging portion sandwiched between the guide pressing member and the guide connecting portion. It was done.

(Operation) With the above configuration, the filter guide is attached to the suction grill by sandwiching the engaging portion between the guide pressing member and the guide connecting portion. Then, in cooperation with both sides of the suction grill, the air filter is guided appropriately.

(Embodiment) An embodiment of the present invention will be described below with reference to the accompanying drawings.

1 and 2 show an embodiment of an intake grill of an indoor unit of an air conditioner according to the present invention,
A part of the configuration similar to the conventional one is omitted.

The suction grill 1 has guide connecting portions 3 at both ends 2 thereof, and a plurality of guide pressing members 4 are provided along the side end 2 at appropriate intervals. The filter guide 5, which is separate from these, is provided with an engaging portion 6 that is sandwiched between the guide connecting portion 3 and the guide pressing member 4.

As shown in FIGS. 3 and 4, the guide connecting portion 3 is formed by also using the back surface of the corrugated panel 7 having a suction port (not shown) as the connecting surface 8, and the filter guide 5 Protrusions 9 are appropriately provided so that the can be supported from the front side.

As shown in FIG. 3, the guide pressing member 4 has a connecting surface 8
And the bent member facing the protrusion 9, and is positioned with a gap S corresponding to the member thickness of the filter guide 5 therebetween, and is formed integrally with the corrugated panel 7. That is, the filter guide 5 can be supported by inserting the engaging portion 6 into the gap S. On the other hand, the connecting portion 3 is provided with a hole 10 corresponding to the projected area of the portion of the guide pressing member 4 that projects in parallel with the suction surface.

As shown in FIG. 5, the filter guide 5 is an elongated member having a stepwise horizontal cross section, and is formed with an air filter support portion 11 that is adjacent to the engagement portion 6 in the transverse direction. That is, when the engaging portion 6 is sandwiched between the guide connecting portion 3 and the pressing member 4, the opposite side is projected so as to press the edge portion of the air filter (not shown). Both ends of the air filter support portion 11 have a gap S
It is formed in a tapered shape so that it can be easily inserted in the vertical direction.

Further, a knob 12 for inserting operation is provided at the center of the filter guide 5 in the longitudinal direction. When the knob 12 is assembled, the knob 12 has such a height that it comes into contact with a heat exchanger (not shown) provided in the indoor unit, and is separated by a distance corresponding to the height. The filter guide 5 is positioned in the front-rear direction.

In addition, as shown in FIG. 2, a stopper 13 for holding the filter guide 5 at a predetermined position is provided on the back surface of the corrugated panel 7, and is vertically moved by a distance corresponding to the length of the filter guide 5. They are separated by the direction.

Next, the operation of this embodiment will be described.

The guide holding member 4 supports the filter guide 5 at a predetermined position by sandwiching the engaging portion 6 of the filter guide 5 against the guide connecting portion 3. In this state, the air filter support portion 11 attaches the air filter to the guide support portion 3
While being held between the protrusion 9 and the protrusion 9, it is guided in parallel with the corrugated panel 7. To assemble this suction grill, hold the knob 12 of the filter guide 5 and insert it from the outside of the holding member 4 in the vertical direction into the gap S along the guide support portion 3 to the position where it abuts the stopper 13. .

In this way, with the guide pressing member 4 and the guide connecting portion 3,
Since the filters are connected so as to sandwich the filter guide 5, an adhesive is not required, which contributes to a reduction in manufacturing cost.
Further, since the filter guide 5 can be easily inserted, it contributes to shortening the assembling time. In addition, there is no risk of adhesion failure, which leads to stable product quality, and also eliminates the trouble of quantitative management of the adhesive.

Further, in manufacturing this suction grill, the pressing member 4 is positioned so as to overlap the guide connecting portion 3,
By die-cutting with the hole 10, integral molding is possible.

In addition, the engaging portion 6, the guide connecting portion 3 of the filter guide 5,
The shape of the guide pressing member 4 is not limited to this embodiment, and may be, for example, a curved shape. Further, the guide pressing member 4 may be provided by an adhesive instead of being integrally molded. However, in this case, since the bonding step remains in the assembly, the effect is limited to the quantity reduction of the adhesive as compared with the conventional configuration.

[Effects of the Invention] In short, according to the present invention, the following excellent effects are exhibited.

Since the guide connecting members formed at both ends of the suction grille are integrally provided with the guide pressing members facing the guide connecting members, and the filter guide is formed with the engaging portion sandwiched between the guide pressing member and the guide connecting portion. Since no adhesive is required, it can contribute to the simplification of the assembly process.
